Abstract

A modified unacknowledge mode of a telecommunications system interface is defined by providing for a special signaling indication by way of a selected packet, signaling sequence, message, or the like, from a transmitting side to a receiving side that a given message, packet, cell, signaling sequence, or the like is to be treated specially, despite the unacknowledge mode being used, by acknowledging receipt thereof at the receiving side back to the transmitting side. In this way, certain important messages can be acknowledged, while less important messages can be sent without acknowledgement. This reduces the need for wasteful use of capacity for applications in which some of the messages are more important than others to be received correctly.

Claims (32)

1. Method for use in a telecommunications system having the capability to exchange information packets over a communications link in both an acknowledge mode in which reception by a receiver of all information packets transmitted by a transmitter over the communications link are acknowledged by the receiver sending at least one acknowledgement over the communications link back to the transmitter and in an unacknowledge mode in which none of the information packets transmitted by the transmitter over the communications link are acknowledged by the receiver, characterized by said transmitter in said unacknowledge mode nevertheless determining from among a plurality of packets destined for transmission to the receiver in said unacknowledge mode a selected packet for which an acknowledgement of receipt from the receiver is required, and signaling said receiver that said acknowledgement of receipt of said selected packet is required from the receiver.
2. The method of claim 1, further characterized by said transmitter after transmitting said selected packet, waiting during a set time period thereafter for receipt of said acknowledgement from said receiver before taking further steps contingent on said acknowledgement of receipt by said receiver.
3. The method of claim 2, further characterized by said transmitter storing the selected packet during said set time period at least until said receipt of said acknowledgement from said receiver.
4. The method of claim 3, further characterized by said transmitter, after said selected packet is transmitted to the receiver, also storing during said set time period packets for which acknowledgement is not required at least until said receipt of said acknowledgement from said receiver.
5. The method of claim 4, further characterized by said transmitter retransmitting to said receiver said stored selected packet and said stored packets for which acknowledgement was not required after said set time elapses without receipt of said acknowledgement from said receiver.
6. The method of claim 3, further characterized by said transmitter retransmitting to said receiver said stored selected packet after said set time elapses without receipt of said acknowledgement from said receiver.
7. The method of claim 6, further characterized by said transmitter receiving over said communications link from said receiver an acknowledgement of receipt of said selected packet and by notifying a higher layer in a protocol stack of the transmitter of said receipt of said selected packet by said receiver.
8. The method of claim 6, further characterized by said transmitter waiting for at least one further set time period after said step of retransmitting said stored selected packet for an acknowledgement of receipt thereof from the receiver before finally concluding that said retransmitted stored selected packet was not received by the receiver.
9. The method of claim 8, further characterized by said transmitter notifying a higher layer in a protocol stack of the transmitter of nonreceipt of said retransmitted stored selected packet.
10. The method of claim 5, further characterized by said transmitter waiting for at least one further set time period after said step of retransmitting said stored selected packet and said stored packets for which acknowledgement was not required, for an acknowledgement of receipt of the stored selected packet from the receiver before finally concluding that said retransmitted stored selected packet was not received by the receiver.
11. The method of claim 10, further characterized by said transmitter notifying a higher layer in a protocol stack of the transmitter of nonreceipt of said retransmitted stored selected packet.
12. The method of claim 2, characterized by said transmitter concluding after lapse of said set time period without receiving said acknowledgement that said selected packet was not received by said receiver.
13. The method of claim 12, further characterized by said transmitter notifying a higher layer in a protocol stack of the transmitter of nonreceipt of said acknowledgement.
14. The method of claim 1, characterized by said receiver in said unacknowledge mode determining reception over said communications link of said selected packet for which acknowledgement of receipt is required, and signaling said acknowledgement of receipt to said transmitter over said communications link.
15. The method of claim 14, characterized by said receiver determining whether said received selected packet was received correctly or not wherein said step of signaling said acknowledgement of receipt to said transmitter indicates correct or incorrect reception.
16. The method of claim 15, characterized by said transmitter storing the selected packet during said set time period at least until receipt of said acknowledgement from said receiver and upon receipt by said transmitter of said acknowledgement indicative of incorrect reception of said selected packet, retransmitting said selected packet.
17. The method of claim 15, characterized by said receiver, after determining the selected packet was received incorrectly, continuing to process incoming packets without any change in processing method therefor.
18. The method of claim 15, characterized by said receiver saving packets received after determining the selected packet was received incorrectly until receiving the selected packet correctly after which the receiver processes incoming packets according to a method identified by said selected packet.
19. The method of claim 1, characterized by said transmitter receiving over said communications link from said receiver an acknowledgement of receipt of said selected packet and by notifying a higher layer in a protocol stack of the transmitter of said receipt of said selected packet by said receiver.
20. Transceiver having a receiving section and a transmitting section for use on both a receiving side and a transmitting side in a communications telecommunications system having the capability to exchange information packets over a communications link in both an acknowledge mode in which reception by a receiver section of a transceiver on the receiving side of all information packets transmitted by the transmitter section of a transceiver on the transmitting side over the communications link are acknowledged by the receiver section sending at least one acknowledgement over the communications link back to the transmitter section and in an unacknowledge mode in which none of the information packets transmitted by the transmitter section over the communications link are acknowledged by the receiver section, characterized by said transmitter section in said unacknowledge mode nevertheless having means for determining from among a plurality of packets destined for transmission to the receiver section in said unacknowledge mode a selected packet for which an acknowledgement of receipt from the receiver section is required, and means for transmitting a signal to said receiver section that said acknowledgement of receipt of said selected packet is required from the receiver section.
